Product classification
HS code for Epsomite: 2530.20
Kieserite, epsomite (natural magnesium sulphates).
Classification of epsomite under HS 2530.20
Epsomite is classified under HS code 253020 as a natural mineral. Chapter 25 of the Harmonized System covers earth, stone, plastering materials, lime, and cement. Specifically, heading 2530 includes mineral substances not elsewhere specified or included, and subheading 253020 is dedicated to kieserite and epsomite, which are natural magnesium sulphates. The classification depends on the product being in its natural state, or having been washed (even with chemical substances to remove impurities), crushed, ground, powdered, levigated, sifted, or screened. If the magnesium sulphate has been produced through a chemical process or refined to a high degree of purity beyond what is found in the natural mineral state, it would move to Chapter 28.

Codes often confused with 2530.20
Common mistake. The most common misclassification for epsomite is HS code 283321. While both codes refer to magnesium sulphate, 283321 is for the chemically manufactured or highly refined version, whereas 253020 is strictly for the natural mineral. Importers often confuse the two when the natural mineral is finely ground, appearing like a chemical product. Another misclassification occurs with 251990 (magnesium oxide/magnesite), but that code is for carbonates and oxides, not sulphates. It is essential to verify the origin and processing method to distinguish between the mineral (Chapter 25) and the chemical (Chapter 28).

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
